Also known as a pedal exerciser? here's a link to one at the sharper image so you know what I'm talking about: Sharper Image : Stationary Bikes : Portable Exercise Cycle Bike. If you have, is it the same as using a reclining bike or is it basically useless? I mean, I like the idea of a something I can used while watching tv and then put away (I used to have a folding bike but that was another time and place) but if it really doesn't give any tone or calorie burn, i don't want it. So, if you've used on, let me know!
